SPECIFICATION forming part of Letters Patent No. 310,726, dated January13, 1885.

Application filed November 25, 1884. (No model.)

1'0 all whom it may concern.-

Be it known that I, Janus ARTHUR Ross, a citizen of the United States,residing at Plymouth, in the county of Luzerne and State 5 ofPennsylvania, have invented certain new and useful Improvements inCar-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain improvements in automatic car-couplings.It consists, essentially,of a gravitating draw- 1 5 bar, suitablesprings adapted to hold the drawbar in position to couple and to releasesaid draw-bar as the cars come together and the springs are compressed,a weight attached to the draw-bar which throws the same into a positionto effect the coupling when its head enters the receiving draw-head onthe opposite car and said draw-bar is released from the springs.

The particular construction and arrangement of the various parts I willnow proceed to point out and describe, reference being had to theaccompanying drawings, in which Figure l is a bottom plan view, partlyin section, showing the arrangement of the 0 springs, the draw-bar beingin position to couple. Fig. 2 is a side elevation, partly in section,showing the draw-bar released from the spring-catch, dotted linesshowing position of draw-bar when coupled. Fig. 3 is a 5 detail.

Referring to said drawings, A. is a round draw-bar supportedby thebearing a,which is secured to the under side of the car-platform. Saiddraw-baris provided on its outer 0 end with a head, 13, formed like aflat arrowhead and on its rear end with the enlarged portion C,whichenters the cylinder D, and is forced forward against the bearing a bythe spring (I. The outward movement of the draw-bar is limited by theshoulder c striking against said bearing a. The cylinder D is secured tothe platform in any desired manner.

E is a weighted arm or lever secured to the draw-bar at right angles tosaid bar and in the same plane as the flat head 13. p

e is a weight secured to the end of the arm E.

F is an arm projecting from the bearing a. On one side of said arm isthe spring-catchf.

c is an enlargement on the upper part of the arm E,with which thespring-catch f engages and holds the draw-bar in a position to couple.

0" is a projection on the upper side of the draw-bar, which limits thedownward swing of the arm E when it is released from the spring-catch.

G is the receiving draw-head on the oppo site car, having the mouth 9and shoulders g. Said mouth 1 is made of such a width and height thatthe flat head of the draw-bar will readily pass into and out of thedraw-head when in a horizontal position, but when in a vertical positionthe shoulders g engage and couple the cars.

\Vhen it is desired to couple the cars, the arm on the draw-bar israised until it engages with the spring-catcl1 the flat arrow-head Bbeing held in a horizontal plane ready to enter the receiving draw-headon the opposite car. As the cars come together the head or" the draw-barstrikes against the inner end of the draw-head, compressing the spring(I and releasing the arm E from the spring-catch f. The weight thentakes efi'ect, causing the arm E to drop to the position shown in dottedlines, Fig. 2, and turns the fiat head of the draw-bar in the draw-headto a vertical position, causing it to engage with theshoulders g andcouple the cars. hen it is desired to uncouple, the arm E is raiseduntil it engages with the spring-catch f, and the head of the draw-barbeing in a horizontal. position is released from the shoulders and thecars are uncoupled. The spring (I in the cylinder normally holds thedraw-bar forward and acts as a buffer as the cars come together.

Having thus fully described myinvention, I claim as new and desire tosecure by Letters Patent-- 1. In a car-coupling, a draw-bar supported bya bearing, and having a flat arrow-head uIO and an enlarged rear end,suitable springs for holding the draw-bar in a position to couple, andaweight adapted to turn the draw-bar and effect the coupling when saiddraw-bar is released from the springs, in combination with a receivingdraw-head provided with suitable shoulders for engaging with the flatarrowhead of the draw-bar when the same is released from the springs andturned by the weight, all arranged and operating substantially as shownand described.

2. The draw-bar A, having the flat arrowhead B, enlarged rear end, 0,weighted arm E, and bearing a, and spring-catch f, in combination withthe draw-head G, having the mouth 9 and shoulders g, substantially asshown and described.

3. The draw-bar A,having the fiat arrowhead B, enlarged rear end, 0, andweighted arm E, the bearing a, cylinder D, spring d, 20 and spring-catchf, in combination with the draw-head G, having the mouth 9 and shoulders9, all arranged and operating substantially as and for the purpose shownand described. 25

In testimony whereof I affix my signature J in presence of twowitnesses.

JAMES ARTHUR ROSS.
